To all whom it may concern:

Be it known that I, MORRIS WINNING, a subject of the King of Great Britain, and a resident'of the city of Ottawa, in the'Province of Ontario and the Dominion of Canada, have invented certain new and useful Improvements in Switches, of which the followingis a full description.

Thls nvention relates to lmprovem'ents 1n switches particularly adapted for use on street railways, narrow gage tracks and on railroads generally, andthe objects of the invention are to permltof the switch belng 'set by'the approaching car or train, so that the desired path of travel may be taken Without'th'e necessity of manually setting the switch, to render the switch operating device water tight, so that it will not deteriorate owing to. exposure to the elements, to simplify the arrangement of the several parts and generally to adapt the same to better perform the functions required ofthem.

With these and other objects in view, the invention .consists. essentially, of the improved construction particularly described and set forth in the following specification and accompanying drawings forming part of the same.

In the drawings,

Figure 1 is a fragmentary plan view of a railroad embodying the present invention.

Fig. 2 is a sectional elevation of the road showing car mechanism designed to coact with the track mechanism.

Fig. 3 is a fragmentary plan View of the track showing the depression with which the car operating device coacts in operating the switch.

Fig. 4 is a sectional elevation of the track showing the car mechanism in position for operating the track mechanism.

Fig. 5 is a perspective view of an alternative form of switch operating mechanism.

Fig. 6 is an end elevation of the same.

Like characters of reference refer to like parts in the several figures.

Referring to the drawings, A represents a railroad of any usual description consisting of the main track B and the side track C which is controlled by the switch operating mechanism D. This switch operating mechanism consists of a pair of boxes or casings 10 and 11 operativ-ely connected by a pipe 12, so that the said casings and pipe will contain the working mechanism and protect the same from moisture, dirt and the like.

the vertically disposed shaft 17 on the upper end of which a star wheel 18 is rigidly mounted. I j d This star wheel is protected by a cover or plate 19 which extends partially above the same only permitting'one arm of the star wheel to project beyond the edges of the same, .so that it may engage with the car.

mechanism E in a manner to be made clear hereafter. j j j The crank end or the shaft 13 ispivotally connected to the rod 20, while the switch 21 is pivotally connected to the rod 22, and the free ends of the rods 20 and 22 lie alongside of each other and are embraced by the spiral spring 23 which is connected to the free end of the said rods in such a manner that while it permits of the switch 21 being opened 011 rotation of the crank shaft 13, will at the same time give the desired yield to prevent breakage taking place should the switch 21 be fouled with stones, dirt or the like.

The car mechanism E consists of a plunger 24: having a roller 25 on the lower end thereof, the said plunger being operatively mounted on the foot board of the car F, and being spring controlled by means of the spiral spring 26.

The upper end of the unger 24: is pro vided with a foot pad 2%, so that it may be readily depressed by the driver, .and on pressure being removed from the foot pad 27, the plunger 24: will immediately re turn to its normal elevated position as shown in Fig. 2.

The roller 25 will coact with the depression 28 between the tracks adjacent to the star wheel 18 and by the use of this roller any undue friction between the plunger and depression is eliminated.

In that form of the invention illustrated in Figs. 5 and 6, the crank shaft 13 coacts with a locking member 30 which consists of a pair of resilient plates 31 adapted to engage with the shaft on each side of the crank portion, the plates 31 being operatively supported by the bracket 32.

It will be seen that the pairs of plates 31,

while being located on opposite sides of the crank portionprovide a space 33 therebetween through which the rods 20 and 22 operate.

When a railroad is equippedwith a device of this nature and the car F is approaching a switch, it is only necessary for l the driver'to depress the plunger 24: causing Should, for instance, the driver desire to continue on. the main track B, the plunger 24% on contacting with the star wheel 18 will rotate the crank shaft, so that the switch 20 21 is opened, permitting the carto'continue inthe desired path of travel.

,Should a following car, however, desire then to take the side track C, the driver depresses the plunger 24 to engage the star wheel'18 and in this manner rotate thecrank shaft l3 to close the switch 21 and thusper- Init of the car taking the side track C. When that type of the invention illustrated in Figs. 5 and 6 is installed in a railroad, it will be seen that there is no possi bility of the crank shaft 13 becoming acci- In other respects the switchis: the facsimile of that already described and n'eed not'further be enlarged upon.

den-tally rotated, as it requires a decided force to rotate, the same, due to the said crank shaft being held between the resilient In this manner the switch mechanism cannot be interfered with by any unauthorized person in any way and the device is always in an operative position.

As many changes could bemade in the above description and many apparently widely different embodiments of my invention within the scope of the claims constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and drawings shall be interpreted as lllustratlve and not in a limited sense.

What I claim as my invention is:

The combination with a railway track, of

track switching means comprising a crank shaft, spring including means operatively connecting the crank shaft to the switch,

and means'coacting with the crank shaft, comprlslng yoke-shaped reslhent members oneach side of the spring including means. Inwitness whereof I have hereunto set my hand in the presence of a witness.
